SICK CLV621-0120 Barcode Scanner Sensor

SICK CLV621-0120 is a fixed‑mount barcode scanner sensor from the CLV62x family designed for robust, long‑range barcode capture on production lines. It is a line scanner with fixed focus and a visible red light source at 655 nm, laser class 2 safety, and it operates from 10 to 30 VDC while drawing about 4.5 W. The unit reads codes from a front reading field at distances from 60 mm up to 730 mm with a scanning frequency up to 400 Hz, and it supports Ethernet connectivity for network integration via Long Range Ethernet interfaces. Housed in an aluminum die‑cast enclosure and equipped with two M12 connectors on a swivel assembly, this scanner is suited for automated packaging, inventory, and line‑side validation where reliable, non‑contact code reading is required. Its optical aperture angle is ≤ 50°, enabling a compact field of view even at extended reading ranges.
